폐기물을 혼합한 유동화토의 토압특성

The objective of this study is to present various properties required in use of materials made by mixing fly ash and silt. There are several advantages of using flowable fill in place of conventional soil backfill. The main advantage is derived from the fact that there is no need to compact this material. In order to investigate possibility of use to flowable fill, various tests are conducted: axial strength test, flow test, CBR test, model test to clarify earth pressure at rest. The mechanical properties of flowable fill mixed clay, flyash are a mount compatible to low strength fill. therefore the materials proposed in this study might be able to use flowable in backfill trench, retaining wall.
